may be engaged between said rollers for feeding and scoring. Said roller, 81 1s secured to a shaft 88, journaled ina bearing boxv 84 upon the bracket 29, said bracket being cut away, as indicated at 85, in order that said bearing boxes 28 and'84 may be.

supported. in spaced parallel relationship above and below the circular track upon the disk 17. Theroller shafts 27 and 88'have tongue and groove Connections, respectively, with shafts 86 and 87 which are j ournaled in the bracket 29 and carry at their outer ends meshing gears 88 and'89 whereby the rollers are driven in unison by power from a the shaft 14 transmit ed by a chain 41,'taking over sprockets 42 and 43 mounted respectively upon said shaft 14 and the shaft 87. The details of construction of this scoringunit, as well as of the other unit shown in the present embodiment of the invention' and tobe later described, are clearly disclosed in-my'pending application Serial No. 685,628, filed January 11, 1924.

The blanks, after having parallel score 3 lines 44 and 45 formed therein by the mechanism .just described, are engaged by feeding.

rollers 46 and 47 at the'next station in the machine, the mechanism at this station being The roller 47 is mounted upon a shaft48, j ournaled in bearings 49 formed vinbrackets 51 extending upwardly from the table 11, and the upper roller 46 is idly mounted upon astud 52 carried by the bracketc51'at the upper end thereof. The shaft48 is adapted to be driven by means of a-belt 58 taking over a pulley 54 upon said shaft and a pulley 55 mounted upon a shaft 56, which is journaled in bearings 57 and 58 depending from the table 11 and carries at its inner end a beveled gear 59, meshing with a'gear 61 upon a shaft 62, which carries at its inner end a beveled gear 68, meslnng with a gear L 64 upon the drive shaft 14.

The feeding unit just described transfers the blanks, from first scoring unit, supported by the bracket 29, ton. second scoring unit which is supported in a similar bracket, indicated by the reference character .65.

This scoring unit is substantially identical 1 with the one already described and comprises a scoring roll-66, which is'provided with-cutting edges 67 adapted to form herringbone score lines 68 upon the blank between the parallel score lines 44 and 45, said roller being mounted upon a shaft 69, jour-- naledin a bearing box 71 supported by the bracket and a feeding roller '72 being mounted beneath said scoring roller 66 and carried upon a shaft 78, journaled in a hearing box 74, the shafts 69 and 78 being connected with shafts 7 5 and 7 6 carrying meshing gears 77 and 7 8. The shaft is driven by means-of a chain 79, taking over sprockets 81 and82 mounted respectively'upon said- Fig. 5.

thebracket108 just beyond the rollers 98 shaft 75 and the shaft 62 hereinbefore referred to, which shaft is journaled in bearings 88 and 84 in the frame.

The next station of the machine is a feeding station, the mechanism at this station being similar to that at the first feeding station, asshown in Fig. 40f thedrawings andalready described. The feeding rollers at this station are indicated by the reference characters 85 and 86, and are mounted re-r spectively upon a stud 87 and a shaft 88, journaled in bracket arms 89 extending upwardly from the table, said shaft 88'being driven by means of a belt 91, taking over a pulley92 upon said shaft 88 and over a pulley 98 upon a shaft 94, which is ournaled in bearings 95 and. 96 depending from the under side of the table 11, said shaft carry- .ing at its inner end a beveled gear 97, meshing with the gear 61 upon the shaft 62',- said feeding rollers being thus driven from the power shaft 14, which drives said shaft 62,

through the medium of the inter-meshing gears '68 and 64.

The blank is next delivered to a forming station, which is shown in detail in 5 of the drawings. At this station, the blanks are fed between forming rollers 98' and 99, which are carried by shaftslOl and 102 journaled in a bearing box 108, the shaft u 102 carrying at its outer end a pulley 104 over which is directed a belt 105, taking over a pulley 106 upon the end of'a shaft 1070f a motor 108, which is mounted in brackets 109 projecting'upwardly from the top of the table '11, this separate drive permitting rotation of the rollers 98 and99 at greater speed than the scoring and feeding rollers hereinbefore described. As the blank is directed between the rollers 98 and 99, it impinges against a forming plate 111 which is curved at its forward end and adapted V to bend the blank upwardly, asshown in A supporting plate 112 is secured to character 118, this strip, in the-present in- I stance, being of the herringbone type which insures the return of the-line of tear to the parallel score lines'44 and 45 in the event that it'should', for' any cause, bedeflected thereform. The blank is bent by the rollers 98 and 99 to cause itto assume the form They may thereafter beremoved v purpose.

shown infF ig. ofthe drawings, "edges thereof being thereafter" interengaged and 'secure'dtogether in th-ewell-kn'own lock and lap seam by any mechanism suitable for this will be apparent that variouschangeamay be made in thefform, construction and arrangement of the parts, without departing from't-hespirit and scope of the invention,

or sacrificing all of its materialadvantages,

the form hereinbefore described being merely a preferred embodiment thereof.
